Configuration

Babel uses some optimisations on wired interfaces. If you have interfaces that Babel mis-detects as wired (e.g. weird tunnelling setups, bridging), you need to specify the -w flag on Babel's command line;

Babel assumes bridged interfaces are wireless, i.e. disables the optimisations on bridged interfaces. The best solution is to un-bridge the interfaces.

Packaging

The OpenWRT package for Babel is out-of-date. Babel's author uses ipkg-buildpackage to build his own packages.
